Description

Technical Field

[0001] This utility model relates to the field of copper and copper alloy processing technology, specifically to a continuous extrusion press clamping and straightening device. Background Technology

[0002] For the copper and copper alloy processing industry, the upward continuous extrusion process has advantages such as short process flow, low cost, and excellent product performance, and has gradually become the leader in the copper processing industry, experiencing rapid development. The copper rod clamping and straightening device is a crucial component of the continuous extrusion press, and the straightening effect of the copper rod directly affects the normal production of the continuous extrusion machine. Traditional straightening and feeding devices mostly consist of a fixed wheel system and a moving wheel system. The moving wheel system shares a common adjustment mechanism, which is simple to operate but provides unsatisfactory straightening results for the copper rod in actual production. The feeding device consists of a power wheel and an auxiliary wheel, with the auxiliary wheel located above the power wheel. If the copper rod straightening effect is poor, the power wheel will rotate under the action of the copper rod, causing irreversible damage to the reducer. Based on the above problems, designing a new type of clamping and straightening device is imperative.

[0003] Existing clamping and feeding devices, such as the adjustable straightening and feeding device for a copper extrusion press disclosed in patent CN201669314U, consist of a transverse straightening device, a longitudinal straightening device, and a power feeding device. While capable of straightening and feeding copper rods, the shared adjustment mechanism of the driving wheel system results in poor straightening performance for copper rods with significant curvature. Furthermore, the driving wheel of the feeding device is located below the auxiliary wheel, causing poorly straightened copper rods to contact it. This results in significant stress on the feed device's reducer due to the drag from the extrusion wheel, leading to substantial damage to the reducer. Therefore, we propose a novel clamping and straightening device for a continuous extrusion press. Utility Model Content
